a great variety of purposes, such as for screens,` radio antennas, orfor `use in connection Withlphototone and television work, and which maynd elcient use in connection with millinery, hairdressing, electricalheating pads and clothing pads, and which on a largely modified scale,may be found emcient in connection with the reinforcement ofcementitious structures.

Other objects and advantages of this invention will be apparent duringthe course of the following detailed description.

In the accompanying drawing, forming a part of this specification, andwherein similar reference characters designate corresponding partsthroughout the several views,

Figure 1 is a face viewofthe improved fabric, showing the improvedrelation of warp and weft yarns and the relation by means of which theyare tied together. l y l Figure 2 is a view of the reverse side ofthefabric of Figure 1, turned from left to right.

Figure 3 is an enlarged view showing the relation of the warp to weft orfiller yarns.

In the drawing, wherein for the purpose of illustration is shown only apreferred embodiment of the invention, the letter A may generallydesignate the improved textile fabric, which is preferably composed ofmetallic Warp threads 10 arranged in definitely spaced parallelism, withwhich are cooperatively associated the fabric weft threads or yarns 11,tied in upon the warp strands 10 by means of threads 12 which spirallyand individually encompass each of the warp threads 10, in an improvedcooperative relation therewith.

In view of the intended use of the fabric, it is essentially porous,since the mainuse will be in 'connection with radio art, as screening orantenna fabric, although the improved fabric of this invention isparticularly well adapted for use as curtain material and whereverscreening or fabric is desirable for use in interior decorating; thefabric being particularly well adapted for such use due to a certaininherent tendency which the same possesses to maintain its originalshape, and the ease with which it may be made yto assume a definiteshape or form.

' i The entire warp is preferably made of the metallic threads `orstrands 10, which' are preferably of electrical conductive material,such as copper, which may be coated orcovered by means of enameling orcotton-winding the same, or enclosing the same in insulation of anyapproved nature. The materialvof the wire warp strands is not to belimited to copper, since4 it is entirely feasible to use `any desirablealloy-or metal to serve a particular purpose; -it even beingwithin thecontemplation of the invention to use silver. Under certaincircumferences the warp strands may be left uncovered. However, in thepreferred instance, as shown in Figure 3, Ielect to cover the wire body15*a of' the 'strands Y10, with 'an' insulation coating 16Wliich Vmay beof any approved nature.

I have foundit most economical to use ordinarycotton-wound copper wire,and thesame may be liquid-coated or impregnated.

The weft yarns 11 may be of any approved nature,` preferably/fof*fibrous material, such as cotton, ray,fsilk,`iworsted, or any othermaterial. In the preferred instance the weft yarns 11 areeach made'ofaplurality of luntwisted parallelstrands,` such as shown in Figure 3 ofthe drawing, which'a're properly tied in and interwoven with thewarpfvwires by means of the spirally wound'tying-in` threadsv 12.

The weft yarns l'lare `each'wovenfirrparallel lengths betweenthewarp'wirs 10; in the -relation shown in the drawing. That is, as moreclearly shown in Figure 3, each weft yarn 11 extends in a plurality ofparallel lengths 17a and 1'7", sinuously laid back and forth across thespaces between three of the adjacent wire strands 10; the strands 17aand 1'7lo all crossing to one side of the intermediate strand 10, asshown in Figure 3, and the bight portions 18, connecting the lengths 17aand 17h, terminating at the wire strands 10 immediately adjacent and atopposite sides of that strand 10 across which the lengths 17EL and 1'!bextend; these bight portions 18 being each tied in to the adjacent wirewarp thread or strand by means of a spirally wound tied-in thread 12. Itis thus to be noted that the sinuously wound ller or weft yarns 11 allcross the respective wire strands 10 at one side of the fabric, as isbest shown in Figure 1, and the wire strands 10 stand more prominentlyexposed at the opposite side, as is best shown in Figure 2. The side ofthe fabric shown in Figure 1 is the right side and it is to beparticularly noted that the tie-in yarns 12 are so positioned as toengage thru the bight portions or loops 18 of adjacent filler threads 11from the upper part 0f the loop of one bight to the lower part oftheloop of another, in crossing relation with the adjacently relatedlengths 17h, as clearly shown in Figure 3. Thus, the tie-in yarns do nottie-in the lengths 17a, which due to the crowded nature of the weft,work themselves out on top and the effect of which is to hide or rathersecrete the tie-in yarns 12 and the adjacent tie-in portions of the warpand weft yarns. This is especially true since the untwisted strands;making up .the weft yarns or threads 11 will .flufat the ffright'' sideof the fabric. This effect is not so pronounced as is shown in thedrawing, due'to dif'` fibrous textile yarns disposed upon one side onlyof the warp.

3. Fabric composed of warp wires in appreciably spaced relation,sinuously wound ller yarns of fibrous material centralized in adjacentpairs of spaces between the warp wires and means connecting said warpwires and the bight portions of the ller wires.

fi. i Fabric composed of Warp wiresin appreciably spaced relation,sinuously Wound ller yarns of fibrous material in adjacent pairs ofspaces bev`tween the warp wires, each weft lengthof the culty in properillustration. The tie-in yarns gsarne being tied in with the alternatewarp wires 12 are quite inconspicuous, due to the fact that they are ofsmall size compared to either the at the bght portions of the filleryarn lengths, each length of weft between the bight portions warp orweft yarns, and the relation as to size thereof crossing a warp wirebetween the spaces between the yarns is somewhat of the `nature shown inFigure 3. f n

The sinuously inter-related weft threadsN may be suitably tied in alongthe selvage or edges' of the fabric, as can quite readilybe.,understood`, and in connection with use ofthe improved textilefabric for radio antenna and screeninguse,

the warp wires may be conductively connected together.

It is to be particularly noted thatthexnie fabric is rather looselymade, andthe spacingof the lengths making up the weftyarns isappreciably closer than the spacing of the wire warp threads. conductiveand flexible, and inherently VHmore rigid than the fibrous weft andtie-in yarns, as can quite readily be appreciated.
